In the episode where cat gets his hand stuck in the pickle jar, cat has to put on a suit so his date won't know that he is a catdog but his hands are stuck in the pickle jar so he has to use dogs hands.
When they are at dinner dog starts to reach for food off of the table and a hand takes a fork and hits dogs hand away to prevent him from eating the food. This couldn't have been cat's hand because they are stuck in the pickle jar so who's hand is it?
